Ios 如何在Swift中使用组合图像创建GMSMarker

我需要在iOS应用程序中为我的谷歌地图屏幕创建一个

GMSMarker

。我需要标记是图像的组合，即通用标记图像和用户图像。 例如：

在这个标记中，我需要适合用户的图像。我的资产中有两个图像。 它试过了

但这返回了一个不完美的图像。 有其他解决办法吗？

注意：这里提供的示例标记图像不是我实际使用的图像。这是一个矩形标记。

这里我为您提供了一些示例代码，您可以尝试一下，它将根据您的需求进行定制/修改：

let marker = GMSMarker()
let lat = Double("13.063754")
let long = Double("80.24358699999993")
marker.position = CLLocationCoordinate2DMake(lat!,long!)

///Creating UIView for Custom Marker
let DynamicView=UIView(frame: CGRectMake(0, 0, 50, 50))
DynamicView.backgroundColor=UIColor.clearColor()

//Creating Marker Pin imageview for Custom Marker
var imageViewForPinMarker : UIImageView
imageViewForPinMarker  = UIImageView(frame:CGRectMake(0, 0, 40, 50));
imageViewForPinMarker.image = UIImage(named:"LocationPin")

//Creating User Profile imageview
var imageViewForUserProfile : UIImageView
imageViewForUserProfile  = UIImageView(frame:CGRectMake(0, 0, 35, 35));
imageViewForUserProfile.image = UIImage(named:"userprofile")

//Adding userprofile imageview inside Marker Pin Imageview
imageViewForPinMarker.addSubview(imageViewForUserProfile)

//Adding Marker Pin Imageview isdie view for Custom Marker
DynamicView.addSubview(imageViewForPinMarker)

//Converting dynamic uiview to get the image/marker icon.
UIGraphicsBeginImageContextWithOptions(DynamicView.frame.size, false, UIScreen.mainScreen().scale)
DynamicView.layer.renderInContext(UIGraphicsGetCurrentContext()!)
let imageConverted: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

marker.icon = imageConverted
marker.map = self.mapView

您想要的是：

let marker = GMSMarker()
let lat = Double("13.063754")
let long = Double("80.24358699999993")
marker.position = CLLocationCoordinate2DMake(lat!,long!)

///Creating UIView for Custom Marker
let DynamicView=UIView(frame: CGRectMake(0, 0, 50, 50))
DynamicView.backgroundColor=UIColor.clearColor()

//Creating Marker Pin imageview for Custom Marker
var imageViewForPinMarker : UIImageView
imageViewForPinMarker  = UIImageView(frame:CGRectMake(0, 0, 40, 50));
imageViewForPinMarker.image = UIImage(named:"LocationPin")

//Creating User Profile imageview
var imageViewForUserProfile : UIImageView
imageViewForUserProfile  = UIImageView(frame:CGRectMake(0, 0, 35, 35));
imageViewForUserProfile.image = UIImage(named:"userprofile")

//Adding userprofile imageview inside Marker Pin Imageview
imageViewForPinMarker.addSubview(imageViewForUserProfile)

//Adding Marker Pin Imageview isdie view for Custom Marker
DynamicView.addSubview(imageViewForPinMarker)

//Converting dynamic uiview to get the image/marker icon.
UIGraphicsBeginImageContextWithOptions(DynamicView.frame.size, false, UIScreen.mainScreen().scale)
DynamicView.layer.renderInContext(UIGraphicsGetCurrentContext()!)
let imageConverted: UIImage = UIGraphicsGetImageFromCurrentImageContext()
UIGraphicsEndImageContext()

marker.icon = imageConverted
marker.map = self.mapView
